Maintaining a healthy circadian rhythm is one of the most powerful things you can do to take charge of your health and well-being. The most direct and powerful way to do this is through controlling your light exposure and constructing an environment that supports the natural rhythms of your biology.

I have created this site to provide you with the most powerful and cutting edge information on light exposure and your health. You will find science & research based information, product reviews, and how-to guides that can take you as far as you want to go, from “just checking it out” to “hardcore biohacker”.

I have dedicated a lot of time to this website and I hope you’re finding a lot of value here. If this information useful please share it with others. You can also say hi on Twitter: @ShawnSeverinsen.
